Embodiments for Carrying Out the Invention

[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0010] <First Embodiment> First, with reference to FIGS. 1 to 3, a rod-shaped cosmetic material feeding container (hereinafter simply referred to as "feeding container") 1 provided with a core chuck member 10 as a rod-shaped cosmetic material holding member according to a first embodiment of the present invention will be described.

[0011] FIG. 1 is a cross-sectional view of the feeding container 1 provided with the core chuck member 10. (a) shows a state where the core chuck member 10 is located at the retracted limit, and (b) is a cross-sectional view taken along line IB-IB in FIG. 1(a). FIG. 2 is a view showing the core chuck member 10. (a) is a front view, (b) is a side view, and (c) is an enlarged cross-sectional view showing the cosmetic material holding portion 11 in the core chuck member 10. FIG. 3 is an enlarged view of the cosmetic material holding portion 11. (a) is a front view, (b) is a side view, (c) is a plan view showing a state before the rod-shaped cosmetic material A is inserted, and (d) is a cross-sectional view taken along line IIID-IIID in FIG. 3(a) in a state where the rod-shaped cosmetic material A is inserted.

[0012] As shown in FIG. 1(a), the feeding container 1 is a container capable of feeding a rod-shaped cosmetic material A having a substantially circular cross-sectional shape. The rod-shaped cosmetic material A is a forming core formed in a rod shape and is used, for example, as an eyebrow pencil, an eyeliner, a lip liner, or the like. The outer diameter dimension of the rod-shaped cosmetic material A is formed slightly larger than the inner diameter dimension of the cosmetic material holding portion 11 (see FIGS. 3(a) and (b)) described later.

[0013] The feeding container 1 includes a front cylinder 20 having a through hole 20a through which the rod-shaped cosmetic material A can move forward and backward, a base cylinder 30 rotatably assembled to the front cylinder 20, and a core chuck member 10 that holds the rod-shaped cosmetic material A. Hereinafter, the direction along the central axis of the through hole 20a in the front cylinder 20 is referred to as the "axial direction", the direction around the central axis of the through hole 20a is referred to as the "circumferential direction", and the radial direction centered on the central axis of the through hole 20a is referred to as the "radial direction". Also, the movement of the rod-shaped cosmetic material A being fed out from the feeding container 1 is referred to as "forward movement", and the movement of the rod-shaped cosmetic material A being retracted into the feeding container 1 is referred to as "backward movement".

[0014] The front cylinder 20 is a cylindrical member in which a through hole 20a penetrating in the axial direction is formed. The front cylinder 20 has a gripping portion 23 that a user grips, and a fitting portion 24 that is formed continuously with the gripping portion 23 in the axial direction and is fitted into the base cylinder 30. The cross-sectional shape of the through hole 20a is similar to the cross-sectional shape of the rod-shaped cosmetic material A and is formed in a substantially circular shape. The gripping portion 23 is formed in a tapered shape in the axial direction such that the outer diameter gradually decreases from the fitting portion 24 side toward the tip.

[0015] On the outer peripheral surface of the fitting portion 24, an annular fitting convex portion 25 that fits into a fitting concave portion 32 (described later) formed in the base cylinder 30 and an O-ring groove 26 where the O-ring 2 is mounted are formed. The O-ring 2 is provided in a compressed state between the front cylinder 20 and the base cylinder 30, thereby generating appropriate resistance when the front cylinder 20 and the base cylinder 30 are relatively rotated. Thereby, the operation feeling of the user can be improved.

[0016] On the inner peripheral surface of the front cylinder 20, a guide groove 21 that protrudes radially outward and guides the core chuck member 10 along the axial direction is extended along the axial direction. As shown in Fig. 1(b), the guide groove 21 is in a knurled shape composed of a plurality of grooves. In the guide groove 21, claw pieces 12 (described later) of the core chuck member 10 are located and a knurl 16 (described later) engages.

[0017] As shown in FIG. 1(a), the guide groove 21 is formed up to the rear end face 22 of the front cylinder 20. The guide groove 21 is formed up to a position in front of the front cylinder 20 without reaching the tip opening 20b of the through hole 20a. As shown in FIG. 1(b), the inner peripheral surface of the front cylinder 20 is formed to have a cross-sectional shape of a knurl with ridges and valleys by providing the guide groove 21.

[0018] As shown in FIG. 1(a), the base cylinder 30 is a member formed in a bottomed cylindrical shape that houses the core chuck member 10 and has a housing hole 33 into which the fitting portion 24 of the front cylinder 20 is fitted. In the housing hole 33, an annular fitting recess 32 into which the fitting convex portion 25 of the front cylinder 20 is fitted and a female screw portion 31 with which a male screw portion 17 (described later) of the core chuck member 10 engages are provided in order from the opening end side.

[0019] The female screw portion 31 is formed spirally on the inner peripheral surface of the base cylinder 30. The female screw portion 31 is formed continuously with the housing hole 33 in the axial direction.

[0020] As shown in FIGS. 2(a) and (b), the core chuck member 10 includes a decorative material holding portion 11 that holds the rod-shaped decorative material A and a base portion 15 on which the decorative material holding portion 11 stands.

[0021] The rod-shaped decorative material A, which is soft, has a small diameter, and has a circular cross-sectional shape, is loaded into the decorative material holding portion 11. Here, the outer diameter of the rod-shaped decorative material A is about φ1.5 to 3.0 [mm].

[0022] The decorative material holding portion 11 includes a plurality (here, a pair) of claw pieces 12 that extend along the axial direction of the rod-shaped decorative material A and hold the outer peripheral surface of the rod-shaped decorative material A, a base portion end face 15a (see FIG. 2(c)) as a bottom face portion that holds the bottom of the rod-shaped decorative material A, and a connecting band 13a as a band portion that connects at least a pair of claw pieces 12 in the circumferential direction at a position axially away from the base portion end face 15a.

[0023] As shown in Fig. 2(c), the claw pieces 12 stand upright axially from the end face 15a of the base portion. The inner circumferential surface of the claw pieces 12 is formed in a curved shape along the outer circumferential surface of the rod-shaped decorative material A. A pair of claw pieces 12 are provided so as to sandwich the rod-shaped decorative material A. The claw pieces 12 are formed of a thin film having a radial thickness of about 0.20 to 0.25 [mm]. Each claw piece 12 has a tapered surface 12d that inclines so as to be separated from the outer circumferential surface of the rod-shaped decorative material A toward the tip end portion.

[0024] The tapered surface 12d is inclined so that the inner diameter, which is the distance between the pair of claw pieces 12, increases toward the tip end portion. By providing the tapered surface 12d, the insertion of the rod-shaped decorative material A into the decorative material holding portion 11 becomes easy, and it is possible to prevent the outer circumference of the rear end portion of the rod-shaped decorative material A from being scraped by the claw pieces 12 when the rod-shaped decorative material A is inserted.

[0025] The end face 15a of the base portion is provided at the axial tip end portion of the base portion 15. The bottom face of the rod-shaped decorative material A abuts against the end face 15a of the base portion.

[0026] The connecting band 13a is formed over the entire circumferential direction and connects all the claw pieces 12 in the circumferential direction. The connecting band 13a may be formed so as to connect only one of the claw pieces 12 in the circumferential direction. That is, the connecting band 13a connects at least a pair of adjacent claw pieces 12 in the circumferential direction.

[0027] As shown in Figs. 3(a) and (b), the connecting band 13a is provided at a position axially separated from the end face 15a of the base portion. Thereby, a space portion 14a is formed between the end face 15a of the base portion and the connecting band 13a. By providing the space portion 14a, the outer circumferential surface of the rod-shaped decorative material A inserted into the decorative material holding portion 11 bites into the space portion 14a, so that the engagement of the rod-shaped decorative material A with the decorative material holding portion 11 can be strengthened. Therefore, even if the rod-shaped decorative material A is likely to move forward axially due to an impact or the like, the outer circumference of the rod-shaped decorative material A is caught by the rear end face of the connecting band 13a, so that the rod-shaped decorative material A can be prevented from coming off.

[0028] The connecting band 13a is provided at a position axially spaced from the tip of the claw piece 12 toward the end face 15a of the base portion. Thereby, a claw piece elastic portion 12e is formed on the tip side of the claw piece 12 relative to the connecting band 13a. Since the claw piece elastic portion 12e expands outward when the rod-shaped decorative material A is inserted into the decorative material holding portion 11, the rod-shaped decorative material A can be smoothly guided into the decorative material holding portion 11.

[0029] As described above, since the decorative material holding portion 11 of the core chuck member 10 has the connecting band 13a that connects the plurality of claw pieces 12 in the circumferential direction at a position spaced from the end face 15a of the base portion that holds the bottom of the rod-shaped decorative material A, the plurality of claw pieces 12 are suppressed from spreading apart from each other. Therefore, since the holding force by which the claw pieces 12 hold the rod-shaped decorative material A is reinforced by the connecting band 13a, the rod-shaped decorative material A can be stably held, and the rod-shaped decorative material A can be prevented from coming out of the decorative material holding portion 11.

[0030] As shown in FIGS. 3(c) and (d), the inner peripheral surface of the connecting band 13a is formed in a curved shape along the outer peripheral surface of the rod-shaped decorative material A. That is, the inner peripheral surface of the connecting band 13a and the inner peripheral surface of the claw piece 12 are continuously formed along the outer peripheral surface of the rod-shaped decorative material A. Thereby, since the inner peripheral surface of the connecting band 13a and the inner peripheral surface of the claw piece 12 are in close contact with the rod-shaped decorative material A over the entire circumference, the rod-shaped decorative material A can be stably held.

[0031] The connecting band 13a is formed of a thin film having a radial thickness of about 0.20 to 0.25 [mm]. That is, the connecting band 13a has substantially the same radial thickness as the claw piece 12 or is slightly smaller. By forming the claw piece 12 and the connecting band 13a of a thin film, the degree of adhesion to the outer periphery of the rod-shaped decorative material A can be made higher than in the case of using a thick claw piece and connecting band. The connecting band 13a has a rib 13c as an engaging portion that protrudes toward the inner periphery and engages with the rod-shaped decorative material A.

[0032] The rib 13c locks the rod-shaped cosmetic material A in a state where the rod-shaped cosmetic material A is loaded into the cosmetic material holding portion 11. Instead of the rib 13c, for example, a knurled protrusion may be formed on the inner circumference of the connecting band 13a.

[0033] As shown in FIG. 2(c), the connecting band 13a has a tapered surface 13d that is inclined so as to separate from the outer peripheral surface of the rod-shaped cosmetic material A toward the tip at the inner peripheral surface of the tip portion away from the end surface 15a of the base portion.

[0034] The tapered surface 13d is inclined so that the inner diameter, which is the distance between the pair of connecting bands 13a, increases toward the tip. By providing the tapered surface 13d, it becomes easier to insert the rod-shaped cosmetic material A into the cosmetic material holding portion 11, and it is possible to prevent the outer periphery of the rear end portion of the rod-shaped cosmetic material A from being scraped by the connecting band 13a when inserting the rod-shaped cosmetic material A.

[0035] As shown in FIGS. 2(a) and (b), the base portion 15 has a knurl 16 that engages with the guide groove 21 in the circumferential direction, a large-diameter portion 19 that is continuously formed axially from the knurl 16, and a male screw portion 17 provided on the large-diameter portion 19.

[0036] The knurl 16 is formed on the outer periphery of the portion between the end surface 15a of the base portion where the claw piece 12 stands and the front end surface 19a of the large-diameter portion 19 of the large-diameter portion 19. The knurl 16 is a flat knurl formed linearly along the axial direction. By engaging the knurl 16 with the guide groove 21 of the front cylinder 20, the relative rotation in the circumferential direction between the front cylinder 20 and the core chuck member 10 is restricted.

[0037] The large-diameter portion 19 is continuously formed axially from the knurl 16. The large-diameter portion 19 is formed with a larger outer diameter than the knurl 16. The front end surface 19a of the large-diameter portion 19 defines the forward limit of the core chuck member 10 in a state of abutting against the rear end surface 22 of the front cylinder 20. The large-diameter portion 19 defines the backward limit of the core chuck member 10 in a state of abutting against the bottom of the base cylinder 30.

[0038] A plurality of male screw portions 17 are provided so as to protrude from the outer periphery of the large-diameter portion 19. The male screw portions 17 are provided at a plurality of locations in the circumferential direction (here, four locations). The male screw portions 17 are screwed into the female screw portion 31 of the base cylinder 30.

[0039] As shown in Fig. 1(a), when the tip cylinder 20 and the base cylinder 30 are relatively rotated with the male screw portion 17 of the core chuck member 10 screwed into the female screw portion 31 of the base cylinder 30, the core chuck member 10 rotates integrally with the tip cylinder 20, so that the core chuck member 10 and the base cylinder 30 relatively rotate. As a result, the male screw portion 17 of the core chuck member 10 rotates with respect to the female screw portion 31, so that the core chuck member 10 moves axially relative to the base cylinder 30. That is, a feeding mechanism is configured to advance and retract the rod-shaped cosmetic material A held by the core chuck member 10 from the tip opening 20b of the through hole 20a of the tip cylinder 20 by the relative rotation of the tip cylinder 20 and the base cylinder 30.

[0040] As described above, in the feeding container 1, a feeding mechanism for feeding the rod-shaped cosmetic material A axially is configured by the base cylinder 30 and the core chuck member 10. When the tip cylinder 20 and the base cylinder 30 are relatively rotated, the core chuck member 10 moves axially forward and backward within the tip cylinder 20 and the base cylinder 30, and the rod-shaped cosmetic material A also moves forward and backward according to the advancement and retraction of the core chuck member 10.

[0041] Specifically, when the user relatively rotates the tip cylinder 20 and the base cylinder 30 in the forward direction, the core chuck member 10 moves axially toward the tip opening 20b of the tip cylinder 20 to advance the rod-shaped cosmetic material A. As a result, the rod-shaped cosmetic material A is fed out from the tip opening 20b. On the other hand, when the user relatively rotates the tip cylinder 20 and the base cylinder 30 in the reverse direction, the core chuck member 10 moves in the reverse direction to retract the rod-shaped cosmetic material A. As a result, the rod-shaped cosmetic material A is retracted.

[0042] <First Modification Example> Subsequently, with reference to Fig. 4, the core chuck member 110 as a rod-shaped cosmetic material holding member according to the first modification example of the first embodiment of the present invention will be described. In addition, the same components as those in the above-described embodiment are denoted by the same reference numerals, and duplicate explanations are omitted as appropriate.

[0043] FIG. 4 is a view showing a core chuck member 110 according to a first modification of the first embodiment of the present invention, (a) is a front view, (b) is a side view, and (c) is a cross-sectional view taken along line IVC-IVC in FIG. 4(a).

[0044] The core chuck member 110 according to this first modification is different from the above-described first embodiment in that it further includes a connecting band 13b in addition to the connecting band 13a.

[0045] As shown in FIGS. 4(a) and (b), the core chuck member 110 includes a decorative material holding portion 111 that holds the bar-shaped decorative material B, and a base portion 15 on which the decorative material holding portion 111 stands.

[0046] The decorative material holding portion 111 is loaded with a bar-shaped decorative material B that is harder than the bar-shaped decorative material A. The bar-shaped decorative material B is formed to have the same outer diameter and length as the bar-shaped decorative material A.

[0047] The decorative material holding portion 111 includes a plurality (here, a pair) of claw pieces 12 that extend along the axial direction of the bar-shaped decorative material B and hold the outer peripheral surface of the bar-shaped decorative material B, a base portion end surface 15a as a bottom surface portion that holds the bottom of the bar-shaped decorative material B, a connecting band 13a as a band portion that connects at least a pair of claw pieces 12 in the circumferential direction at a position axially away from the base portion end surface 15a, and a connecting band 13b as a band portion that connects at least a pair of claw pieces 12 in the circumferential direction at a position axially away from the connecting band 13a.

[0048] The connecting band 13a is formed over the entire circumferential direction and connects all the claw pieces 12 in the circumferential direction. The connecting band 13a may be formed to connect only one of the claw pieces 12 in the circumferential direction. That is, the connecting band 13a connects at least an adjacent pair of claw pieces 12 in the circumferential direction.

[0049] The connecting band 13b is provided at a position axially separated from the connecting band 13a toward the tip side. The connecting band 13b is formed over the entire circumferential direction and connects all the claw pieces 12 in the circumferential direction. The connecting band 13b may be formed to connect only one of the claw pieces 12 in the circumferential direction. That is, the connecting band 13b connects at least a pair of adjacent claw pieces 12 in the circumferential direction.

[0050] By providing the connecting band 13b, a decorative material holding portion 112e that holds the bar-shaped decorative material B is formed from the end face 15a of the base portion to the tip of the connecting band 13b. Since the bar-shaped decorative material B is harder than the bar-shaped decorative material A, the bar-shaped decorative material B can be inserted into the decorative material holding portion 111 relatively smoothly without using the elasticity of the claw piece elastic portion.

[0051] The connecting band 13b is provided at a position axially away from the end face 15a of the base portion in the claw piece 12 as compared with the connecting band 13a. Thereby, the axial length of the decorative material holding portion 112e can be increased. That is, the axial length of the bar-shaped decorative material B held by the decorative material holding portion 112e can be increased.

[0052] A space portion 14b is further formed between the connecting band 13a and the connecting band 13b. By providing the space portion 14b together with the space portion 14a, the outer peripheral surface of the bar-shaped decorative material B inserted into the decorative material holding portion 111 bites into the space portion 14a and the space portion 14b, so that the engagement of the bar-shaped decorative material B with the decorative material holding portion 111 can be strengthened. Therefore, even if the bar-shaped decorative material B is likely to move forward axially due to an impact or the like, the outer periphery of the bar-shaped decorative material B is caught by the rear end faces of the connecting band 13a and the connecting band 13b, so that the bar-shaped decorative material B can be prevented from coming off.

[0053] Thus, the decorative material holding portion 111 of the core chuck member 110 has a connecting band 13a that connects a plurality of claw pieces 12 in the circumferential direction at a position spaced apart from the end face 15a of the base portion that holds the bottom of the rod-shaped decorative material B, and a connecting band 13b that connects the plurality of claw pieces 12 in the circumferential direction at a position axially spaced apart from the connecting band 13a. Therefore, the plurality of claw pieces 12 are suppressed from spreading apart from each other. Accordingly, since the holding force by which the claw pieces 12 hold the rod-shaped decorative material B is reinforced by the connecting band 13a and the connecting band 13b, the rod-shaped decorative material B can be stably held.

[0054] Further, by forming the decorative material holding portion 112e, the spread of the tip side of the claw piece 12 is suppressed, and the rod-shaped decorative material B can be held long in the axial direction. Therefore, the holding force for holding the rod-shaped decorative material B is further reinforced.

[0055] The inner circumferential surface of the connecting band 13b is formed in a curved shape so as to follow the outer circumferential surface of the rod-shaped decorative material B. That is, the inner circumferential surface of the connecting band 13b and the inner circumferential surface of the claw piece 12 are continuously formed so as to follow the outer circumferential surface of the rod-shaped decorative material B. The connecting band 13b is formed of a thin film having a radial thickness of about 0.20 to 0.25 [mm], similar to the connecting band 13a. That is, the connecting band 13b has substantially the same radial thickness as the claw piece 12 or is slightly smaller. By forming the claw piece 12 and the connecting band 13b of a thin film, the degree of adhesion to the outer circumference of the rod-shaped decorative material B can be made higher than in the case of using a thick claw piece and connecting band.

[0056] Note that ribs 13c are provided on the connecting band 13a, but no ribs are provided on the connecting band 13b. Thereby, a portion that becomes an undercut during molding is eliminated, and the mold release of the mold during molding can be facilitated.

[0057] <Second Modification Example> Subsequently, with reference to FIG. 5, a core chuck member 910 as a rod-shaped decorative material holding member according to a second modification example of the first embodiment of the present invention will be described. Note that the same reference numerals are given to the same configurations as those in the above-described embodiment, and redundant explanations are appropriately omitted.

[0058] FIG. 5 is a view showing a core chuck member 910 according to a second modification of the first embodiment of the present invention, (a) is a front view, (b) is a side view, (c) is a cross-sectional view taken along the VC-VC line in FIG. 5(a), and (d) is a cross-sectional view taken along the VD-VD line in FIG. 5(a).

[0059] The core chuck member 910 according to this second modification is different from the above-described first embodiment in that the connecting band 13a has a tongue portion 13e.

[0060] As shown in FIGS. 5(a) and 5(b), the core chuck member 910 includes a decorative material holding portion 911 that holds the rod-shaped decorative material B, and a base portion 15 on which the decorative material holding portion 911 stands.

[0061] The decorative material holding portion 911 is loaded with a rod-shaped decorative material B that is harder than the rod-shaped decorative material A. The rod-shaped decorative material B is formed to have the same outer diameter and length as the rod-shaped decorative material A.

[0062] The decorative material holding portion 911 includes a plurality (here, a pair) of claw pieces 12 that extend along the axial direction of the rod-shaped decorative material B and hold the outer peripheral surface of the rod-shaped decorative material B, a base portion end surface 15a as a bottom surface portion that holds the bottom portion of the rod-shaped decorative material B, and a connecting band 13a as a band portion that connects at least a pair of claw pieces 12 in the circumferential direction at a position axially away from the base portion end surface 15a.

[0063] The connecting band 13a has a tongue portion 13e that extends axially from the connecting band 13a and has a curved inner peripheral surface along the outer peripheral surface of the rod-shaped decorative material B. In the second modification, the connecting band 13a is not provided with ribs 13c (see FIGS. 3(a), 3(c), and 3(d)).

[0064] The tongue portion 13e is provided in a space portion 14a formed between the end face 15a of the base portion and the connecting band 13a. The tongue portion 13e extends axially from the connecting band 13a toward the end face 15a of the base portion and is formed to have a length up to in front of the end face 15a of the base portion. That is, the tongue portion 13e does not reach the end face 15a of the base portion, and a space portion 14a is secured between the tongue portion 13e and the end face 15a of the base portion. The free end portion of the tongue portion 13e on the side close to the end face 15a of the base portion is formed in an arc shape (curved shape) that is substantially semi-circular along the circumferential direction.

[0065] As described above, since the decorative material holding portion 911 of the core chuck member 910 has the tongue portion 13e that extends axially from the connecting band 13a and has a curved inner peripheral surface along the outer peripheral surface of the bar-shaped decorative material B, the outer peripheral surface of the bar-shaped decorative material B can be held long along the axial direction. Therefore, since the holding force by which the claw piece 12 holds the bar-shaped decorative material B is reinforced by the tongue portion 13e, the bar-shaped decorative material B can be stably held.

[0066] The connecting band 13a is provided at the same axial position as the connecting band 13b of the first modification example as the tongue portion 13e is provided. Therefore, a decorative material holding portion 912e that holds the bar-shaped decorative material B is formed from the end face 15a of the base portion to the tip of the connecting band 13a. Since the bar-shaped decorative material B is harder than the bar-shaped decorative material A, the bar-shaped decorative material B can be inserted into the decorative material holding portion 911 relatively smoothly without using the elasticity of the claw piece elastic portion.

[0067] The inner peripheral surface of the connecting band 13a is formed in a curved shape so as to follow the outer peripheral surface of the bar-shaped decorative material B. That is, the inner peripheral surface of the connecting band 13a and the inner peripheral surface of the claw piece 12 are continuously formed so as to follow the outer peripheral surface of the bar-shaped decorative material B. The connecting band 13a is formed of a thin film having a radial thickness of about 0.20 to 0.25 [mm]. On the other hand, the tongue portion 13e is formed of an extremely thin film having a radial thickness of about 0.10 [mm]. That is, the tongue portion 13e is formed to have a smaller radial thickness than the connecting band 13a. Therefore, the adhesion degree of the tongue portion 13e to the outer periphery of the bar-shaped decorative material B can be increased.

[0068] In addition, by forming the cosmetic material holding portion 912e, the spread of the tip side of the nail piece 12 is suppressed, and the rod-shaped cosmetic material B can be held long in the axial direction. Therefore, the holding force for holding the rod-shaped cosmetic material B is further strengthened.

[0069] According to the above-described first embodiment, the following effects can be obtained.

[0070] The core chuck member 10 that holds the rod-shaped cosmetic material A in the feeding container 1 includes a plurality of nail pieces 12 that extend along the axial direction of the rod-shaped cosmetic material A and hold the outer peripheral surface of the rod-shaped cosmetic material A, a base portion end surface 15a that holds the bottom portion of the rod-shaped cosmetic material A, and at least a pair of nail pieces 12 connected in the circumferential direction at a position axially away from the base portion end surface 15a, and a connecting band 13a that forms a space portion 14a between the connecting band 13a and the base portion end surface 15a.

[0071] According to this configuration, the cosmetic material holding portion 11 of the core chuck member 10 has a connecting band 13a that connects a plurality of nail pieces 12 in the circumferential direction at a position separated from the base portion end surface 15a that holds the bottom portion of the rod-shaped cosmetic material A. Therefore, the plurality of nail pieces 12 are suppressed from spreading apart from each other. Therefore, the rod-shaped cosmetic material A can be stably held, and the rod-shaped cosmetic material A can be prevented from coming out of the cosmetic material holding portion 11. And by providing the space portion 14a, the outer peripheral surface of the rod-shaped cosmetic material A inserted into the cosmetic material holding portion 11 bites into the space portion 14a, so that the engagement of the rod-shaped cosmetic material A with the cosmetic material holding portion 11 can be strengthened. Therefore, even if the rod-shaped cosmetic material A is likely to move forward in the axial direction due to an impact or the like, the outer periphery of the rod-shaped cosmetic material A is caught by the rear end surface of the connecting band 13a, so that the rod-shaped cosmetic material A can be prevented from coming out.

[0072] In addition, the connecting band 13a has a rib 13c that protrudes toward the inner circumference and engages with the rod-shaped cosmetic material A.

[0073] According to this configuration, in a state where the rod-shaped cosmetic material A is loaded in the cosmetic material holding portion 11, the rib 13c engages with the rod-shaped cosmetic material A, so that the rod-shaped cosmetic material A can be locked.

[0074] Further, the inner peripheral surface of the connecting band 13a and the inner peripheral surface of the claw piece 12 are continuously formed along the outer peripheral surface of the rod-shaped cosmetic material A.

[0075] According to this configuration, since the inner peripheral surface of the connecting band 13a and the inner peripheral surface of the claw piece 12 are in close contact with the rod-shaped cosmetic material A over the entire circumference, the rod-shaped cosmetic material A can be stably held.

[0076] Further, the connecting band 13a has a tapered surface 13d that is inclined so as to be spaced apart from the outer peripheral surface of the rod-shaped cosmetic material A toward the tip at the inner peripheral surface of the tip portion away from the end surface 15a of the base portion.

[0077] According to this configuration, the provision of the tapered surface 13d facilitates the insertion of the rod-shaped cosmetic material A into the cosmetic material holding portion 11 and can prevent the outer periphery of the rear end portion of the rod-shaped cosmetic material A from being scraped by the connecting band 13a when the rod-shaped cosmetic material A is inserted.

[0078] Further, the connecting band 13a is provided at a position spaced from the tip of the claw piece 12 toward the end surface 15a of the base portion.

[0079] According to this configuration, a claw piece elastic portion 12e is formed on the tip side of the claw piece 12 with respect to the connecting band 13a. The claw piece elastic portion 12e expands outward when the rod-shaped cosmetic material A is inserted into the cosmetic material holding portion 11, so that the rod-shaped cosmetic material A can be smoothly guided into the cosmetic material holding portion 11.

[0080] <Second Embodiment> Next, with reference to FIGS. 6 to 11, a rod-shaped cosmetic material feeding container 201 including a core chuck member 210 as a rod-shaped cosmetic material holding member according to the second embodiment of the present invention will be described. In addition, the same components as those in the above-described embodiment are denoted by the same reference numerals, and redundant descriptions will be omitted as appropriate.

[0081] FIG. 6 is a cross-sectional view of the feeding container 201 including the core chuck member 210, where (a) shows the state where the core chuck member 210 is located at the retracted limit, and (b) is a cross-sectional view taken along line VIB-VIB in FIG. 6(a). FIG. 7 is a view showing the core chuck member 210, where (a) is a front view, (b) is a side view, and (c) is an enlarged cross-sectional view showing the cosmetic holding portion 211 of the core chuck member 210. FIG. 8 is an enlarged view of the cosmetic holding portion 211, where (a) is a front view, (b) is a plan view showing the state before the rod-shaped cosmetic A is inserted, and (c) is a cross-sectional view taken along line VIIIC-VIIIC in FIG. 8(a) in the state where the rod-shaped cosmetic A is inserted.

[0082] As shown in FIG. 6(a), the feeding container 201 includes a front cylinder 220 having a through hole 20a through which the rod-shaped cosmetic A can advance and retreat, a base cylinder 230 assembled to the front cylinder 220 so as to be relatively rotatable, a core chuck member 210 that holds the rod-shaped cosmetic A, and a female screw cylinder 240 provided in the base cylinder 230 so as not to be relatively rotatable with respect to the base cylinder 230.

[0083] The front cylinder 220 is a cylindrical member in which a through hole 20a penetrating in the axial direction is formed. The front cylinder 220 has a gripping portion 223 that a user grips, and a fitting portion 224 that is formed continuously with the gripping portion 223 in the axial direction and is fitted into the base cylinder 230. The cross-sectional shape of the through hole 20a is similar to the cross-sectional shape of the rod-shaped cosmetic A and is formed in a substantially circular shape. The gripping portion 223 is formed in a tapered shape in the axial direction so that the outer diameter gradually decreases from the fitting portion 224 side toward the tip.

[0084] On the outer peripheral surface of the fitting portion 224, an annular fitting convex portion 225 that fits into a fitting concave portion 232 (described later) formed in the base cylinder 230 and an O-ring groove 226 in which the O-ring 2 is mounted are formed. The O-ring 2 is provided in a compressed state between the front cylinder 220 and the base cylinder 230, thereby generating an appropriate resistance when the front cylinder 220 and the base cylinder 230 are relatively rotated. Thereby, the operating feeling of the user can be improved.

[0085] On the inner circumferential surface of the front cylinder 220, a guide groove 221 that protrudes radially outward and guides the core chuck member 210 along the axial direction is extended along the axial direction. As shown in FIG. 6(b), the guide groove 221 is a linear groove provided at intervals in the circumferential direction (here, four). In the guide groove 221, a claw piece 212 (described later) of the core chuck member 210 is located, and an engaging strip portion 216 (described later) engages. Wall strip portions 222 are respectively formed between adjacent guide grooves 221.

[0086] As shown in FIG. 6(a), the guide groove 221 is formed up to the rear end surface 222a of the front cylinder 220. The guide groove 221 is formed up to before the front end opening 20b of the through hole 20a without reaching it.

[0087] The base cylinder 230 is a member formed in a bottomed cylindrical shape that houses the core chuck member 210 and into which the fitting portion 224 of the front cylinder 220 is fitted and the female screw cylinder 240 is inserted. In the housing hole 233, an annular fitting recess 232 into which the fitting convex portion 225 of the front cylinder 220 is fitted is provided.

[0088] As shown in FIGS. 7(a) and 7(b), the core chuck member 210 includes a decorative material holding portion 211 that holds the rod-shaped decorative material A, and a base portion 215 on which the decorative material holding portion 211 stands.

[0089] The decorative material holding portion 211 includes a plurality (here, four) of claw pieces 212 that extend along the axial direction of the rod-shaped decorative material A and hold the outer circumferential surface of the rod-shaped decorative material A, a base portion end surface 215a (see FIG. 7(c)) as a bottom surface portion that holds the bottom of the rod-shaped decorative material A, and a connecting band 213 as a band portion that connects at least a pair of claw pieces 212 in the circumferential direction at a position axially away from the base portion end surface 215a.

[0090] As shown in FIG. 7(c), the claw pieces 212 stand upright axially from the end face 215a of the base portion. The outer peripheral surface of the claw piece 212 is formed to have a smaller diameter than the outer peripheral surface of the engaging strip portion 216 in the base portion 215. The inner peripheral surface of the claw piece 212 is formed in a curved shape along the outer peripheral surface of the rod-shaped decorative material A. Four claw pieces 212 are provided so as to sandwich the outer periphery of the rod-shaped decorative material A in a cross shape. Each claw piece 212 has a tapered surface 212d that inclines so as to be spaced apart from the outer peripheral surface of the rod-shaped decorative material A toward the tip, and an inner peripheral convex portion 212c that protrudes inward and engages with the rod-shaped decorative material A as an engaging portion.

[0091] The tapered surface 212d is inclined so that the inner diameter, which is the distance between a pair of opposing claw pieces 212, increases toward the tip. By providing the tapered surface 212d, the insertion of the rod-shaped decorative material A into the decorative material holding portion 211 becomes easier, and it is possible to prevent the outer periphery of the rear end portion of the rod-shaped decorative material A from being scraped by the claw pieces 212 when the rod-shaped decorative material A is inserted.

[0092] The inner peripheral convex portion 212c locks the rod-shaped decorative material A in a state where the rod-shaped decorative material A is loaded in the decorative material holding portion 211. The inner peripheral convex portion 212c is formed within the range of a claw piece elastic portion 212e, which will be described later. Note that, instead of the inner peripheral convex portion 212c, for example, a knurled protrusion may be formed on the inner periphery of the claw piece 212.

[0093] The end face 215a of the base portion is provided at the axial tip of the base portion 215. The bottom surface of the rod-shaped decorative material A abuts against the end face 215a of the base portion.

[0094] The connecting band 213 is formed over the entire circumferential direction and connects all the claw pieces 212 in the circumferential direction. The connecting band 213 may be formed so as to connect only a part of the claw pieces 212 in the circumferential direction. That is, the connecting band 213 connects at least a pair of adjacent claw pieces 212 in the circumferential direction.

[0095] As shown in FIGS. 7(a) to (c), the connecting band 213 is provided at a position axially spaced from the end face 215a of the base portion. Thereby, a space portion 214a is formed between the end face 215a of the base portion and the connecting band 213. By providing the space portion 214a, the outer peripheral surface of the rod-shaped cosmetic material A inserted into the cosmetic material holding portion 211 bites into the space portion 214a, so that the engagement of the rod-shaped cosmetic material A with the cosmetic material holding portion 211 can be strengthened. Therefore, even if the rod-shaped cosmetic material A is likely to move forward in the axial direction due to an impact or the like, the outer periphery of the rod-shaped cosmetic material A is caught by the rear end face of the connecting band 213, so that the rod-shaped cosmetic material A can be prevented from coming off.

[0096] As shown in FIG. 8(a), the connecting band 213 is provided at a position axially spaced from the tip of the claw piece 212 toward the end face 215a of the base portion. Thereby, a claw piece elastic portion 212e is formed on the tip side of the claw piece 212 with respect to the connecting band 213. Since the claw piece elastic portion 212e expands outward when the rod-shaped cosmetic material A is inserted into the cosmetic material holding portion 211, the rod-shaped cosmetic material A can be smoothly guided into the cosmetic material holding portion 211.

[0097] Thus, since the cosmetic material holding portion 211 of the core chuck member 210 has the connecting band 213 that connects the plurality of claw pieces 212 in the circumferential direction at a position spaced from the end face 215a of the base portion that holds the bottom of the rod-shaped cosmetic material A, the plurality of claw pieces 212 are suppressed from spreading apart from each other. Therefore, since the holding force by which the claw piece 212 holds the rod-shaped cosmetic material A is reinforced by the connecting band 213, the rod-shaped cosmetic material A can be stably held, and the rod-shaped cosmetic material A can be prevented from coming out of the cosmetic material holding portion 211.

[0098] As shown in FIGS. 8(b) and (c), the inner peripheral surface of the connecting band 213 is formed in a curved shape along the outer peripheral surface of the rod-shaped cosmetic material A. That is, the inner peripheral surface of the connecting band 213 and the inner peripheral surface of the claw piece 212 are continuously formed along the outer peripheral surface of the rod-shaped cosmetic material A. Thereby, since the inner peripheral surface of the connecting band 213 and the inner peripheral surface of the claw piece 212 are in close contact with the rod-shaped cosmetic material A over the entire circumference, the rod-shaped cosmetic material A can be stably held.

[0099] The connecting band 213 is formed of a thin film having a radial thickness of about 0.10 [mm]. The connecting band 213 has a smaller radial thickness than the claw piece 212. As a result, the claw piece 212 protrudes radially outward more than the connecting band 213, so that the claw piece 212 can be positioned within the guide groove 221 of the front cylinder 220.

[0100] As shown in FIGS. 7(a) and (b), the base portion 215 has an engaging strip portion 216 that engages with the guide groove 221 in the circumferential direction, and a male screw portion 217 that is continuously formed axially from the engaging strip portion 216.

[0101] The engaging strip portion 216 is formed on the outer periphery of a portion between the base portion end face 215a where the claw piece 212 stands and the male screw portion 217. The engaging strip portion 216 is formed linearly along the axial direction. The engaging strip portion 216 is continuously formed axially from the claw piece 212. By engaging the engaging strip portion 216 with the guide groove 221 of the front cylinder 220, the relative rotation in the circumferential direction between the front cylinder 220 and the core chuck member 210 is restricted. A groove portion is formed between adjacent engaging strip portions 216 up to the groove portion end face 219. The groove portion end face 219 defines the forward limit of the core chuck member 210 in a state of abutting against the rear end face 222a of the wall strip portion 222 in the front cylinder 220. Also, the rearward limit of the core chuck member 210 is defined in a state where the rear end face of the base portion 215 abuts against the bottom of the base cylinder 230.

[0102] A plurality of male screw portions 217 are provided so as to protrude from the outer periphery of a portion that is continuously formed axially from the engaging strip portion 216 and has a smaller diameter than the engaging strip portion 216. The male screw portions 217 are provided at a plurality of locations in the circumferential direction (here, two locations) and at a plurality of locations in the axial direction. The male screw portions 217 are screwed into the female screw portion 243 of the female screw cylinder 240.

[0103] As shown in Fig. 6(a), the female screw cylinder 240 is a resin cylindrical member in which a female screw portion 243, with which the male screw portion 217 of the core chuck member 210 engages, is formed to penetrate axially. The female screw cylinder 240 has a rear end face 244 that abuts against the stepped portion 235 of the base cylinder 230 when inserted into the base cylinder 230, and a front end face 242 that abuts against the rear end face 222a of the front cylinder 220 when the front cylinder 220 is assembled to the base cylinder 230.

[0104] On the outer peripheral surface of the female screw cylinder 240, a plurality of longitudinal ribs (not shown) extending in the axial direction are formed at equal intervals in the circumferential direction. The longitudinal ribs engage with a knurl (not shown) formed on the inner peripheral surface of the base cylinder 230 and function as a rotation stopper to prevent the female screw cylinder 240 from rotating relative to the base cylinder 230.

[0105] When the front cylinder 220 and the base cylinder 230 are relatively rotated with the male screw portion 217 of the core chuck member 210 screwed into the female screw portion 243 of the female screw cylinder 240, the core chuck member 210 rotates integrally with the front cylinder 220, and the female screw cylinder 240 rotates integrally with the base cylinder 230. Thus, the core chuck member 210 and the base cylinder 230 rotate relative to each other. As a result, the male screw portion 217 of the core chuck member 210 rotates relative to the female screw portion 243, and the core chuck member 210 moves axially relative to the female screw cylinder 240. That is, a feeding mechanism is configured to advance and retract the bar-shaped cosmetic material A held by the core chuck member 210 from the tip opening 20b of the through hole 20a of the front cylinder 220 by the relative rotation of the front cylinder 220 and the base cylinder 230.

[0106] In this way, in the feeding container 201, a feeding mechanism for feeding the bar-shaped cosmetic material A axially is configured by the female screw cylinder 240 and the core chuck member 210. When the front cylinder 220 and the base cylinder 230 are relatively rotated, the core chuck member 210 moves axially forward and backward within the front cylinder 220 and the base cylinder 230, and the bar-shaped cosmetic material A also moves forward and backward according to the forward and backward movement of the core chuck member 210.

[0107] Specifically, when the user relatively rotates the front cylinder 220 and the base cylinder 230 in the forward direction, the core chuck member 210 moves axially toward the front end opening 20b of the front cylinder 220 to advance the rod-shaped cosmetic material A. As a result, the rod-shaped cosmetic material A is fed out from the front end opening 20b. On the other hand, when the user relatively rotates the front cylinder 220 and the base cylinder 230 in the reverse direction, the core chuck member 210 moves in the reverse direction to retract the rod-shaped cosmetic material A. As a result, the rod-shaped cosmetic material A is rewound.

[0108] <First Modification Example> Subsequently, with reference to FIG. 9, the core chuck member 310 as a rod-shaped cosmetic material holding member according to the first modification example of the second embodiment of the present invention will be described. Note that the same reference numerals are given to the same configurations as those in the above-described embodiment, and redundant descriptions will be omitted as appropriate.

[0109] FIG. 9 is a view showing the core chuck member 310, (a) is a front view, (b) is a plan view showing a state before the rod-shaped cosmetic material A is inserted, and (c) is a cross-sectional view taken along line IXC-IXC in FIG. 9(a) in a state where the rod-shaped cosmetic material A is inserted.

[0110] The core chuck member 310 according to this first modification example is different from the second embodiment described above in that the connecting band 213 is not formed over the entire circumferential direction but is formed only in a part of the circumferential direction.

[0111] As shown in FIG. 9(a), the core chuck member 310 includes a cosmetic material holding portion 311 that holds the rod-shaped cosmetic material A, and a base portion 215 on which the cosmetic material holding portion 311 stands.

[0112] The cosmetic material holding portion 311 includes a plurality (here, four) of claw pieces 212 that extend along the axial direction of the rod-shaped cosmetic material A and hold the outer peripheral surface of the rod-shaped cosmetic material A, a base portion end surface 215a as a bottom surface portion that holds the bottom of the rod-shaped cosmetic material A, and a connecting band 213 as a band portion that connects the pair of claw pieces 212 in the circumferential direction at a position axially away from the base portion end surface 215a.

[0113] The connecting band 213 connects a pair of adjacent claw pieces 212 to form a pair of opposing holding pieces 311a and 311b. The holding pieces 311a and 311b are not connected by the connecting band.

[0114] The connecting band 213 is provided at a position axially spaced from the end face 215a of the base portion. Thereby, a space portion 214a is formed between the end face 215a of the base portion and the connecting band 213. By providing the space portion 214a, the outer peripheral surface of the rod-shaped cosmetic material A inserted into the cosmetic material holding portion 311 bites into the space portion 214a, so that the engagement of the rod-shaped cosmetic material A with the cosmetic material holding portion 311 can be strengthened. Therefore, even if the rod-shaped cosmetic material A is likely to move forward in the axial direction due to an impact or the like, the outer periphery of the rod-shaped cosmetic material A is caught by the rear end face of the connecting band 213, so that the rod-shaped cosmetic material A can be prevented from coming off.

[0115] The connecting band 213 is provided at a position axially spaced from the tip of the claw piece 212 toward the end face 215a of the base portion. Thereby, a claw piece elastic portion 212e is formed on the tip side of the claw piece 212 with respect to the connecting band 213. The claw piece elastic portion 212e expands outward when the rod-shaped cosmetic material A is inserted into the cosmetic material holding portion 311, so that the rod-shaped cosmetic material A can be smoothly guided into the cosmetic material holding portion 311.

[0116] In this way, the cosmetic material holding portion 311 of the core chuck member 310 has a connecting band 213 that circumferentially connects a pair of adjacent claw pieces 212 at a position spaced from the end face 215a of the base portion that holds the bottom of the rod-shaped cosmetic material A. Therefore, the expansion of the pair of connected claw pieces 212 so as to be separated from each other is suppressed. Therefore, since the holding force of the claw pieces 212 for holding the rod-shaped cosmetic material A is reinforced by the connecting band 213, the rod-shaped cosmetic material A can be stably held, and the rod-shaped cosmetic material A can be prevented from coming out of the cosmetic material holding portion 311.

[0117] <Second Modification Example> Next, with reference to FIG. 10, the core chuck member 410 as a rod-shaped cosmetic material holding member according to the second modification of the second embodiment of the present invention will be described. In addition, the same components as those in the above-described embodiments are denoted by the same reference numerals, and redundant descriptions will be omitted as appropriate.

[0118] FIG. 10 is a view showing the core chuck member 410. (a) is a front view, (b) is a plan view showing the state before the rod-shaped cosmetic material A is inserted, and (c) is a cross-sectional view taken along the line XC-XC in FIG. 10(a) in the state where the rod-shaped cosmetic material A is inserted.

[0119] The core chuck member 410 according to this second modification is different from the above-described second embodiment in that ribs 412c are provided on the claw pieces 212 instead of the inner peripheral convex portions 212c.

[0120] As shown in FIGS. 10(a) to (c), the core chuck member 410 includes a cosmetic material holding portion 411 that holds the rod-shaped cosmetic material A, and a base portion 215 on which the cosmetic material holding portion 411 stands.

[0121] The cosmetic material holding portion 411 includes a plurality (here, four) of claw pieces 212 that extend along the axial direction of the rod-shaped cosmetic material A and hold the outer peripheral surface of the rod-shaped cosmetic material A, a base portion end surface 215a as a bottom surface portion that holds the bottom portion of the rod-shaped cosmetic material A, and a connecting band 213 as a band portion that connects at least a pair of claw pieces 212 in the circumferential direction at a position axially away from the base portion end surface 215a.

[0122] The claw pieces 212 stand axially from the base portion end surface 215a. The outer peripheral surface of the claw piece 212 is formed to have a smaller diameter than the outer peripheral surface of the engaging strip portion 216 in the base portion 215. The inner peripheral surface of the claw piece 212 is formed in a curved shape so as to follow the outer peripheral surface of the rod-shaped cosmetic material A. Four claw pieces 212 are provided so as to sandwich the outer periphery of the rod-shaped cosmetic material A in a cross shape. Each claw piece 212 has a tapered surface 212d that inclines away from the outer peripheral surface of the rod-shaped cosmetic material A toward the tip, and a rib 412c as an engaging portion that projects toward the inner periphery and engages with the rod-shaped cosmetic material A.

[0123] The rib 412c is linearly formed along the axial direction from the end face 215a of the base portion. The rib 412c is formed up to a position closer to the tip than the connecting band 213. The rib 412c locks the bar-shaped cosmetic material A in a state where the bar-shaped cosmetic material A is loaded into the cosmetic material holding portion 411. Note that, instead of the rib 412c, for example, a knurled protrusion may be formed on the inner circumference of the claw piece 212.

[0124] Thus, even when the rib 412c is provided on the claw piece 212 instead of the inner peripheral convex portion 212c, in a state where the bar-shaped cosmetic material A is loaded into the cosmetic material holding portion 411, the rib 412c engages with the bar-shaped cosmetic material A, thereby locking the bar-shaped cosmetic material A.

[0125] <Third Modification Example> Next, with reference to FIG. 11, a core chuck member 510 as a bar-shaped cosmetic material holding member according to a third modification example of the second embodiment of the present invention will be described. Note that the same reference numerals are given to the same configurations as those in the above-described embodiments, and redundant descriptions will be omitted as appropriate.

[0126] FIG. 11 is a view showing the core chuck member 510. (a) is a front view, (b) is a plan view showing a state before the bar-shaped cosmetic material B is inserted, and (c) is a cross-sectional view taken along the line XIC-XIC in FIG. 11(a) in a state where the bar-shaped cosmetic material B is inserted.

[0127] The core chuck member 510 according to this third modification example is different from the second modification example of the second embodiment described above in that the width of the claw piece 512 is formed smaller than that of the claw piece 212, and the connecting band 513 is formed at a position closer to the tip of the claw piece 512 than the rib 512c.

[0128] As shown in FIGS. 11(a) to (c), the core chuck member 510 includes a cosmetic material holding portion 511 that holds the bar-shaped cosmetic material B, and a base portion 215 on which the cosmetic material holding portion 511 stands.

[0129] The cosmetic material holding portion 511 includes a plurality (here, four) of claw pieces 512 that extend along the axial direction of the rod-shaped cosmetic material B and hold the outer peripheral surface of the rod-shaped cosmetic material B, a base portion end surface 215a as a bottom surface portion that holds the bottom portion of the rod-shaped cosmetic material B, and a connecting band 513 as a band portion that connects at least a pair of claw pieces 512 in the circumferential direction at a position axially away from the base portion end surface 215a.

[0130] The claw pieces 512 stand upright axially from the base portion end surface 215a. The outer peripheral surface of the claw piece 512 is formed to have a smaller diameter than the outer peripheral surface of the engaging strip portion 216 in the base portion 215. The inner peripheral surface of the claw piece 512 is formed in a curved shape along the outer peripheral surface of the rod-shaped cosmetic material B. Four claw pieces 512 are provided so as to sandwich the outer periphery of the rod-shaped cosmetic material B in a cross shape. The claw pieces 512 are formed to have a smaller width (circumferential length) than the claw pieces 212. Thereby, the circumferential distance between adjacent claw pieces 512 can be increased. Each claw piece 512 has a tapered surface 512d that inclines so as to be separated from the outer peripheral surface of the rod-shaped cosmetic material B toward the tip end portion, and a rib 512c as an engaging portion that protrudes toward the inner periphery and engages with the rod-shaped cosmetic material B.

[0131] The tapered surface 512d is inclined so that the inner diameter, which is the distance between a pair of opposing claw pieces 512, increases toward the tip end portion. By providing the tapered surface 512d, the insertion of the rod-shaped cosmetic material B into the cosmetic material holding portion 511 becomes easy, and it is possible to prevent the outer periphery of the rear end portion of the rod-shaped cosmetic material B from being scraped by the claw pieces 512 when the rod-shaped cosmetic material B is inserted.

[0132] The rib 512c is formed linearly along the axial direction from the base portion end surface 215a. The rib 512c is provided within the range of a cosmetic material holding portion 512e described later. The rib 512c is formed to a position axially away from the tip end from the connecting band 513. That is, the rib 512c is formed to the length from the base portion end surface 215a to in front of the connecting band 513. The rib 512c locks the rod-shaped cosmetic material B in a state where the rod-shaped cosmetic material B is loaded in the cosmetic material holding portion 511. Instead of the rib 512c, for example, a knurled protrusion may be formed on the inner periphery of the claw piece 512.

[0133] The connecting band 513 is formed across the entire circumferential direction and connects all the claw pieces 512 in the circumferential direction. The connecting band 513 may be formed to connect only a part of the claw pieces 512 in the circumferential direction. That is, the connecting band 513 connects at least a pair of adjacent claw pieces 512 in the circumferential direction.

[0134] The connecting band 513 is provided at a position axially spaced from the end face 215a of the base portion. Thereby, a space portion 514a is formed between the end face 215a of the base portion and the connecting band 513. By providing the space portion 514a, the outer peripheral surface of the rod-shaped cosmetic material B inserted into the cosmetic material holding portion 511 bites into the space portion 514a, so that the engagement of the rod-shaped cosmetic material B with the cosmetic material holding portion 511 can be strengthened. Therefore, even if the rod-shaped cosmetic material B is likely to move forward in the axial direction due to an impact or the like, since the outer periphery of the rod-shaped cosmetic material B is caught by the rear end face of the connecting band 513, it is possible to prevent the rod-shaped cosmetic material B from coming off.

[0135] The connecting band 513 is provided at a position axially spaced from the tip of the claw piece 512 toward the end face 215a of the base portion. By providing the connecting band 513, a cosmetic material holding portion 512e that holds the rod-shaped cosmetic material B is formed from the end face 215a of the base portion to the tip of the connecting band 513. Since the rod-shaped cosmetic material B is harder than the rod-shaped cosmetic material A, the rod-shaped cosmetic material B can be inserted into the cosmetic material holding portion 511 relatively smoothly without using the elasticity of the claw piece elastic portion.

[0136] The connecting band 513 is provided at a position axially farther from the end face 215a of the base portion in the claw piece 512 than the connecting band 213. Thereby, the axial length of the cosmetic material holding portion 512e can be increased. That is, the axial length of the rod-shaped cosmetic material B held by the cosmetic material holding portion 512e can be increased.

[0137] Thus, since the decorative material holding portion 511 of the core chuck member 510 has the connecting band 513 that connects a plurality of claw pieces 512 in the circumferential direction at a position separated from the end face 215a of the base portion that holds the bottom portion of the rod-shaped decorative material B, the plurality of claw pieces 512 are suppressed from spreading apart from each other. Therefore, since the holding force with which the claw pieces 512 hold the rod-shaped decorative material B is reinforced by the connecting band 513, the rod-shaped decorative material B can be stably held.

[0138] Further, since the decorative material holding portion 512e is formed, the spreading of the tip side of the claw piece 512 is suppressed, and the rod-shaped decorative material B can be held long in the axial direction. Therefore, the holding force for holding the rod-shaped decorative material B is further reinforced.

[0139] The inner circumferential surface of the connecting band 513 is formed in a curved shape so as to follow the outer circumferential surface of the rod-shaped decorative material B. That is, the inner circumferential surface of the connecting band 513 and the inner circumferential surface of the claw piece 512 are continuously formed so as to follow the outer circumferential surface of the rod-shaped decorative material B. Thereby, since the inner circumferential surface of the connecting band 513 and the inner circumferential surface of the claw piece 512 are in close contact with the rod-shaped decorative material B over the entire circumference, the rod-shaped decorative material B can be stably held.

[0140] The connecting band 513 is formed of a thin film having a radial thickness of about 0.10 [mm]. The connecting band 513 has a smaller radial thickness than the claw piece 512. Thereby, since the claw piece 512 protrudes radially outward more than the connecting band 513, the claw piece 512 can be positioned within the guide groove 221 of the front cylinder 220.

[0141] The connecting band 513 has a large circumferential length by being formed such that the width of the claw piece 512 is smaller than that of the claw piece 212. That is, in the decorative material holding portion 511, the circumferential length of the portion formed of the thin film becomes large. Since the connecting band 513 formed of the thin film has a higher degree of adhesion to the outer circumferential surface of the rod-shaped decorative material B than the claw piece 512, the rear outer circumferential surface of the rod-shaped decorative material B is held so as to fit exactly to the inner circumference of the cavity portion formed by the claw piece 512 and the connecting band 513. Therefore, the rod-shaped decorative material B can be stably held.

[0142] According to the above-described second embodiment, the same effects as those of the first embodiment are achieved, and the following effects are also achieved.

[0143] The connecting band 213 has a smaller radial thickness than the claw piece 212.

[0144] According to this configuration, since the claw piece 212 protrudes radially outward more than the connecting band 213, the claw piece 212 can be positioned within the guide groove 221 of the front cylinder 220.

[0145] <Third Embodiment> Next, with reference to FIGS. 12 to 16, a rod-shaped cosmetic material feeding container (hereinafter simply referred to as "feeding container") 601 including a core chuck member 610 as a rod-shaped cosmetic material holding member according to a third embodiment of the present invention will be described. In addition, the same components as those in the above-described embodiments are denoted by the same reference numerals, and redundant descriptions will be omitted as appropriate.

[0146] FIG. 12 is a cross-sectional view of the feeding container 601 including the core chuck member 610. (a) shows a state where the core chuck member 610 is located at the retracted limit, (b) shows a state where the core chuck member 610 is located at the advanced limit, and (c) is a cross-sectional view taken along line XIIC-XIIC in FIG. 12(b). FIG. 13 is a view showing the core chuck member 610. (a) is a side view, (b) is a front view, and (c) is an enlarged cross-sectional view showing the cosmetic material holding portion 611 of the core chuck member 610. FIG. 14 is an enlarged view of the cosmetic material holding portion 611. (a) is a side view, (b) is a front view, (c) is a plan view showing a state before the rod-shaped cosmetic material C is inserted, and (d) is a cross-sectional view taken along line XIVD-XIVD in FIG. 14(b) in a state where the rod-shaped cosmetic material C is inserted.

[0147] As shown in FIGS. 12(a) and (b), the feeding container 601 is a container capable of feeding a rod-shaped cosmetic material C having a substantially elliptical cross-sectional shape. The rod-shaped cosmetic material C is a forming core formed into a rod shape and is used, for example, as an eyebrow pencil, an eyeliner, a lip liner, or the like. The rod-shaped cosmetic material C is softer than the rod-shaped cosmetic material B, similar to the rod-shaped cosmetic material A. The outer diameter dimension of the rod-shaped cosmetic material C is formed slightly larger than the inner diameter dimension of a cosmetic material holding portion 611 described later. The ratio of the minor axis to the major axis of the rod-shaped cosmetic material C is approximately 1:2. Specifically, for example, the minor axis of the rod-shaped cosmetic material C is about 1.5 [mm], and the major axis is about 3.0 [mm].

[0148] The feeding container 601 includes a front cylinder 620 having a through hole 20a through which the rod-shaped cosmetic material C can advance and retreat, a base cylinder 630 assembled to be relatively rotatable with respect to the front cylinder 620, a core chuck member 610 that holds the rod-shaped cosmetic material C, and a female screw cylinder 640 provided in the base cylinder 630 so as not to be relatively rotatable with respect to the base cylinder 630.

[0149] The front cylinder 620 is a cylindrical member in which a through hole 20a penetrating in the axial direction is formed. The front cylinder 620 has a picking portion 623 that a user picks and a fitting portion 624 that is formed continuously with the picking portion 623 in the axial direction and is fitted into the base cylinder 630. The cross-sectional shape of the through hole 20a is similar to the cross-sectional shape of the rod-shaped cosmetic material C and is formed in a substantially elliptical shape. The picking portion 623 is formed in a tapered shape in the axial direction such that the outer diameter gradually decreases from the fitting portion 624 side toward the tip.

[0150] On the outer peripheral surface of the fitting portion 624, an annular fitting convex portion 625 that fits into a fitting concave portion 632 (described later) formed in the base cylinder 630 and an O-ring groove 626 in which an O-ring 2 is mounted are formed. The O-ring 2 is provided in a compressed state between the front cylinder 620 and the base cylinder 630, thereby generating an appropriate resistance when the front cylinder 620 and the base cylinder 630 are relatively rotated. Thereby, the operating feeling of the user can be improved.

[0151] On the inner peripheral surface of the front cylinder 620, there is a guide groove 621 that protrudes radially outward and guides the core chuck member 610 along the axial direction, which extends along the axial direction. As shown in FIG. 12(c), the guide grooves 621 are linear grooves provided at intervals in the circumferential direction (here, six). In the guide groove 621, a claw piece 612 (described later) of the core chuck member 610 is located, and an engaging strip portion 616 (described later) engages. Wall strip portions 622 are respectively formed between adjacent guide grooves 621.

[0152] The guide groove 621 is formed up to the rear end surface 622a of the front cylinder 620. The guide groove 621 is formed up to before the tip opening 20b of the through hole 20a without reaching it.

[0153] The base cylinder 630 is a member formed in a bottomed cylindrical shape that houses the core chuck member 610 and into which the fitting portion 624 of the front cylinder 620 is fitted and the female screw cylinder 640 is inserted. In the housing hole 633, an annular fitting recess 632 into which the fitting convex portion 625 of the front cylinder 620 is fitted is provided.

[0154] As shown in FIGS. 13(a) and (b), the core chuck member 610 includes a decorative material holding portion 611 that holds the bar-shaped decorative material C, and a base portion 615 on which the decorative material holding portion 611 stands.

[0155] The decorative material holding portion 611 includes a plurality (here, six) of claw pieces 612 that extend along the axial direction of the bar-shaped decorative material C and hold the outer peripheral surface of the bar-shaped decorative material C, a base portion end surface 615a (see FIG. 13(c)) as a bottom surface portion that holds the bottom of the bar-shaped decorative material C, and a connecting band 613 as a band portion that connects at least a pair of claw pieces 612 in the circumferential direction at a position axially away from the base portion end surface 615a.

[0156] As shown in Fig. 13(c), the claw pieces 612 stand upright axially from the end face 615a of the base portion. The outer peripheral surface of the claw piece 612 is formed to have a smaller diameter than the outer peripheral surface of the engaging strip portion 616 in the base portion 615. The inner peripheral surface of the claw piece 612 is formed in a curved shape along the outer peripheral surface of the rod-shaped decorative material C. Six claw pieces 612 are provided so as to sandwich the rod-shaped decorative material C from the outside. The claw piece 612 has a plurality of short claw pieces 612a with a small length from the end face 615a of the base portion and a plurality of long claw pieces 612b with a length larger than that of the short claw piece 612a from the end face 615a of the base portion.

[0157] The short claw pieces 612a are respectively provided at both ends of the long axis of the rod-shaped decorative material C. The short claw pieces 612a hold the rod-shaped decorative material C from both ends of the long axis respectively.

[0158] Two long claw pieces 612b are provided between the short claw pieces 612a. The two long claw pieces 612b are provided so as to face each other across the central axis. The long claw pieces 612b are provided at a position closer to the central axis than the short claw pieces 612a. The long claw pieces 612b are formed to have a larger thickness than the short claw pieces 612a.

[0159] As shown in Figs. 12(a) and (b), in a state where the core chuck member 610 is located at the forward limit, by forming the short claw piece 612a on the short axis side shorter than the long claw piece 612b, the outer diameter in the tip direction on the short axis side of the tip cylinder 620 can be reduced. Thereby, the taper on the short axis side in the picking portion 623 of the tip cylinder 620 can be reduced toward the tip. Since it is possible to prevent the tip portion of the tip cylinder 620 from hitting the face when applying makeup around the eyes if the outer diameter on the tip side of the tip cylinder 620 is small, the feeding container 601 can be made easier to use.

[0160] As shown in Fig. 13(c), each long claw piece 612b has a tapered surface 612d that inclines so as to be separated from the outer peripheral surface of the rod-shaped decorative material C toward the tip portion.

[0161] The tapered surface 612d is formed to be inclined such that the inner diameter, which is the distance between a pair of long claw pieces 612 facing each other, increases toward the tip end portion. By providing the tapered surface 612d, the insertion of the rod-shaped cosmetic material C into the cosmetic material holding portion 611 becomes easy, and it is possible to prevent the outer periphery of the rear end portion of the rod-shaped cosmetic material C from being scraped by the long claw pieces 612 when inserting the rod-shaped cosmetic material C.

[0162] The base portion end face 615a is provided at the axial tip end portion of the base portion 615. The bottom face of the rod-shaped cosmetic material C abuts against the base portion end face 615a.

[0163] As shown in FIGS. 14(a) and (b), the connecting band 613 is formed over the entire circumferential direction and connects all the claw pieces 612 in the circumferential direction. The connecting band 613 may be formed to connect only some of the claw pieces 612 in the circumferential direction. That is, the connecting band 613 connects at least a pair of adjacent claw pieces 612 in the circumferential direction. The connecting band 613 includes a first connecting band 613a that connects the circumferential direction between the adjacent short claw piece 612a and the long claw piece 612b, and a second connecting band 613b that connects the circumferential direction between a pair of adjacent long claw pieces 612b.

[0164] The connecting band 613 is provided at a position axially spaced apart from the base portion end face 615a. Thereby, a first space portion 614a is formed between the base portion end face 615a and the first connecting band 613a, and a second space portion 614b is formed between the base portion end face 615a and the second connecting band 613b. By providing the first space portion 614a and the second space portion 614b, the outer peripheral surface of the rod-shaped cosmetic material C inserted into the cosmetic material holding portion 611 bites into the first space portion 614a and the second space portion 614b, so that the engagement of the rod-shaped cosmetic material C with the cosmetic material holding portion 611 can be strengthened. Therefore, even if the rod-shaped cosmetic material C is likely to move forward in the axial direction due to an impact or the like, the outer periphery of the rod-shaped cosmetic material C is caught by the rear end faces of the first connecting band 613a and the second connecting band 613b, so that the rod-shaped cosmetic material C can be prevented from coming off.

[0165] The connecting band 613 is provided at a position axially spaced from the tip of the claw piece 612 toward the end face 615a of the base portion. As a result, a claw piece elastic portion 612e is formed on the tip side of the claw piece 612 with respect to the connecting band 613. Since the claw piece elastic portion 612e expands outward in the radial direction when the rod-shaped decorative material C is inserted into the decorative material holding portion 611, the rod-shaped decorative material C can be smoothly guided into the decorative material holding portion 611.

[0166] As described above, since the decorative material holding portion 611 of the core chuck member 610 has the connecting band 613 that connects the plurality of claw pieces 612 in the circumferential direction at a position spaced from the end face 615a of the base portion that holds the bottom of the rod-shaped decorative material C, the plurality of claw pieces 612 are suppressed from expanding so as to be separated from each other. Therefore, since the holding force by which the claw pieces 612 hold the rod-shaped decorative material C is reinforced by the connecting band 613, the rod-shaped decorative material C can be stably held, and the rod-shaped decorative material C can be prevented from coming out of the decorative material holding portion 611.

[0167] The inner peripheral surface of the connecting band 613 is formed in a curved shape so as to follow the outer peripheral surface of the rod-shaped decorative material C. That is, the inner peripheral surface of the connecting band 613 and the inner peripheral surface of the claw piece 612 are continuously formed so as to follow the outer peripheral surface of the rod-shaped decorative material C. As a result, since the inner peripheral surface of the connecting band 613 and the inner peripheral surface of the claw piece 612 are in close contact with the rod-shaped decorative material C over the entire circumference, the rod-shaped decorative material C can be stably held.

[0168] The connecting band 613 is formed of a thin film having a radial thickness of about 0.10 [mm]. The connecting band 613 has a smaller radial thickness than the claw piece 612. As a result, the claw piece 612 protrudes radially outward more than the connecting band 613, so that the claw piece 612 can be positioned within the guide groove 621 of the front cylinder 620.

[0169] As shown in FIGS. 13(a) and (b), the base portion 615 has an engaging strip portion 616 that engages with the guide groove 621 in the circumferential direction, and a male screw portion 617 that is continuously formed axially from the engaging strip portion 616.

[0170] The engaging strip portion 616 is formed on the outer periphery of the portion between the base portion end face 615a where the claw piece 612 stands and the male screw portion 617. The engaging strip portion 616 is formed linearly along the axial direction. The engaging strip portion 616 is formed continuously from the claw piece 612 in the axial direction. When the engaging strip portion 616 engages with the guide groove 621 of the front cylinder 620, the relative rotation in the circumferential direction between the front cylinder 620 and the core chuck member 610 is restricted. The engaging strip portion 616 has a first engaging strip portion 616a formed continuously from the short claw piece 612a and a second engaging strip portion 616b formed continuously from the long claw piece 612b. A groove portion is formed up to the groove portion end face 619 between adjacent second engaging strip portions 616b. The groove portion end face 619 defines the forward limit of the core chuck member 610 in a state of abutting against the rear end face 622a of the wall strip portion 622 in the front cylinder 620.

[0171] A plurality of male screw portions 617 are provided so as to project from the outer periphery of a portion formed continuously from the engaging strip portion 616 in the axial direction and having a smaller diameter than the engaging strip portion 616. The male screw portions 617 are provided at a plurality of locations (here, two locations) in the circumferential direction. The male screw portions 617 are screwed into the female screw portion 643 of the female screw cylinder 640.

[0172] As shown in FIGS. 12(a) and (b), the female screw cylinder 640 is a resin-made cylindrical member in which a female screw portion 643 into which the male screw portion 617 of the core chuck member 610 is screwed is formed to penetrate in the axial direction. The female screw cylinder 640 has a rear end face 644 that abuts against the stepped portion 635 of the base cylinder 630 when inserted into the base cylinder 630, and a front end face 642 that abuts against the rear end face 622a of the front cylinder 620 when the front cylinder 620 is assembled to the base cylinder 630.

[0173] A plurality of longitudinal ribs (not shown) extending in the axial direction are formed on the outer peripheral surface of the female screw cylinder 640 at equal intervals in the circumferential direction. The longitudinal ribs engage with a knurl (not shown) formed on the inner peripheral surface of the base cylinder 630 and function as a rotation stopper to prevent the female screw cylinder 640 from rotating with respect to the base cylinder 630.

[0174] With the male screw portion 617 of the core chuck member 610 screwed into the female screw portion 643 of the female screw cylinder 640, when the tip cylinder 620 and the base cylinder 630 are relatively rotated, the core chuck member 610 rotates integrally with the tip cylinder 620, and the female screw cylinder 640 rotates integrally with the base cylinder 630. Therefore, the core chuck member 610 and the base cylinder 630 rotate relative to each other. As a result, the male screw portion 617 of the core chuck member 610 rotates with respect to the female screw portion 643, so that the core chuck member 610 moves axially relative to the female screw cylinder 640. That is, a feeding mechanism is configured to advance and retract the rod-shaped cosmetic material C held by the core chuck member 610 from the tip opening 20b of the through hole 20a of the tip cylinder 620 by the relative rotation of the tip cylinder 620 and the base cylinder 630.

[0175] In this way, in the feeding container 601, a feeding mechanism for feeding the rod-shaped cosmetic material C axially is configured by the female screw cylinder 640 and the core chuck member 610. When the tip cylinder 620 and the base cylinder 630 are relatively rotated, the core chuck member 610 moves axially forward and backward in the tip cylinder 620 and the base cylinder 630, and the rod-shaped cosmetic material C also moves forward and backward according to the advance and retreat of the core chuck member 610.

[0176] Specifically, when the user relatively rotates the tip cylinder 620 and the base cylinder 630 in the forward direction, the core chuck member 610 moves axially toward the tip opening 20b of the tip cylinder 620 to advance the rod-shaped cosmetic material C. As a result, the rod-shaped cosmetic material C is fed out from the tip opening 20b. On the other hand, when the user relatively rotates the tip cylinder 620 and the base cylinder 630 in the reverse direction, the core chuck member 610 moves in the reverse direction to retract the rod-shaped cosmetic material C. As a result, the rod-shaped cosmetic material C is retracted. The engaging strip portion 616 of the core chuck member 610 is formed so as not to allow the female screw cylinder 640 to pass through. Therefore, as the core chuck member 610 retracts, the engaging strip portion 616 abuts against the female screw cylinder 640, and the retraction limit of the core chuck member 610 is defined.

[0177] <First Modified Example> Next, with reference to FIG. 15, a core chuck member 710 as a rod-shaped cosmetic material holding member according to a first modification of the third embodiment of the present invention will be described. In addition, the same components as those in the above-described embodiment are denoted by the same reference numerals, and redundant descriptions will be omitted as appropriate.

[0178] FIG. 15 is a diagram showing the core chuck member 710, where (a) is a side view, (b) is a front view, (c) is a plan view showing a state before the rod-shaped cosmetic material C is inserted, (d) is a cross-sectional view taken along the line XVD-XVD in FIG. 15(b), and (e) is a cross-sectional view corresponding to FIG. 12(c).

[0179] The core chuck member 710 according to this first modification is different from the above-described third embodiment in that the connecting band 613 is not formed over the entire circumferential direction but only in a part of the circumferential direction.

[0180] As shown in FIGS. 15(a) to (e), the core chuck member 710 includes a cosmetic material holding portion 711 that holds the rod-shaped cosmetic material C, and a base portion 615 on which the cosmetic material holding portion 711 stands.

[0181] The cosmetic material holding portion 711 includes a plurality (here, six) of claw pieces 612 that extend along the axial direction of the rod-shaped cosmetic material C and hold the outer peripheral surface of the rod-shaped cosmetic material C, a base portion end surface 615a as a bottom surface portion that holds the bottom portion of the rod-shaped cosmetic material C, and a connecting band 613 as a band portion that connects three claw pieces 612 in the circumferential direction at a position axially away from the base portion end surface 615a.

[0182] The connecting band 613 connects a pair of long claw pieces 612b adjacent to the short claw piece 612a to form a pair of opposing holding pieces 711a and 711b. The holding pieces 711a and 711b are not connected by the connecting band 613. That is, the connecting band 613 has only the first connecting band 613a and does not have the second connecting band 613b.

[0183] The first connecting band 613a is provided at a position axially spaced from the end face 615a of the base portion. As a result, a first space portion 614a is formed between the end face 615a of the base portion and the first connecting band 613a. By providing the first space portion 614a, the outer peripheral surface of the rod-shaped cosmetic C inserted into the cosmetic holding portion 711 bites into the first space portion 614a, so that the engagement of the rod-shaped cosmetic C with the cosmetic holding portion 711 can be strengthened. Therefore, even if the rod-shaped cosmetic C is likely to move forward in the axial direction due to an impact or the like, the outer periphery of the rod-shaped cosmetic C is caught by the rear end face of the first connecting band 613a, so that the rod-shaped cosmetic C can be prevented from coming off.

[0184] The first connecting band 613a is provided at a position axially spaced from the tip of the short claw piece 612a toward the end face 615a of the base portion. As a result, a claw piece elastic portion 612e is formed on the tip side of the short claw piece 612a and the long claw piece 612b with respect to the first connecting band 613a. Since the claw piece elastic portion 612e expands outward when the rod-shaped cosmetic C is inserted into the cosmetic holding portion 711, the rod-shaped cosmetic C can be smoothly guided into the cosmetic holding portion 711.

[0185] As described above, the cosmetic holding portion 711 of the core chuck member 710 has a first connecting band 613a that circumferentially connects a pair of long claw pieces 612b adjacent to the short claw piece 612a at a position spaced from the end face 615a of the base portion that holds the bottom of the rod-shaped cosmetic C. Therefore, the connected claw pieces 612 are suppressed from expanding so as to be separated from each other. Therefore, since the holding force of the claw pieces 612 for holding the rod-shaped cosmetic C is reinforced by the first connecting band 613a, the rod-shaped cosmetic C can be stably held, and the rod-shaped cosmetic C can be prevented from coming out of the cosmetic holding portion 711.

[0186] In addition, in this first modified example, the distance between the wall strip portions 722 formed between the pair of guide grooves 621 where the pair of long claw pieces 612b adjacent to each other are located is smaller than the wall strip portion 622 of the third embodiment shown in FIG. 12(c). Thereby, in the first modified example, at a position where the first connecting band 613a is not provided, the clearance between the outer peripheral surface of the bar-shaped decorative material C and the wall strip portion 722 can be minimized. Therefore, when the core chuck member 710 moves forward and backward, the outer peripheral surface of the bar-shaped decorative material C in the minor axis direction can be constantly supported along the axial direction by the opposing wall strip portions 722. Therefore, it is possible to prevent the core from breaking due to the inclination of the bar-shaped decorative material C and to stabilize the forward and backward movement of the bar-shaped decorative material C. And even when the bar-shaped decorative material C that is soft, has a thin core diameter, is long in core length, and is easily broken is filled and the feeding stroke is long, it is possible to prevent the core from breaking due to the inclination of the bar-shaped decorative material C from the retraction limit to the forward limit of the core chuck member 710.

[0187] <Second Modified Example> Subsequently, with reference to FIG. 16, the core chuck member 810 as a bar-shaped decorative material holding member according to the second modified example of the third embodiment of the present invention will be described. In addition, the same components as those in the above-described embodiments are denoted by the same reference numerals, and redundant descriptions are omitted as appropriate.

[0188] FIG. 16 is a view showing the core chuck member 810, (a) is a side view, (b) is a front view, (c) is a plan view showing a state before the bar-shaped decorative material C is inserted, (d) is a cross-sectional view taken along line XVID-XVID in FIG. 16(b), and (e) is a cross-sectional view taken along line XVIE-XVIE in FIG. 16(b).

[0189] The core chuck member 810 according to this second modified example is different from the above-described third embodiment in that the axial positions where the first connecting band 613a and the second connecting band 813b are provided are different.

[0190] As shown in FIGS. 16(a) to (e), the core chuck member 810 includes a decorative material holding portion 811 that holds the bar-shaped decorative material C, and a base portion 615 on which the decorative material holding portion 811 stands.

[0191] The cosmetic material holding part 811 includes a plurality (here, six) of claw pieces 612 that extend along the axial direction of the rod-shaped cosmetic material C and hold the outer peripheral surface of the rod-shaped cosmetic material C, a base part end surface 615a as a bottom surface part that holds the bottom part of the rod-shaped cosmetic material C, and a connecting band 613 as a band part that connects a pair of claw pieces 612 in the circumferential direction at a position axially away from the base part end surface 615a.

[0192] The connecting band 613 has a first connecting band 613a that connects between adjacent short claw pieces 612a and long claw pieces 612b in the circumferential direction, and a second connecting band 813b that connects between adjacent pairs of long claw pieces 612b in the circumferential direction.

[0193] The first connecting band 613a is provided at a position axially spaced apart from the base part end surface 615a. Thereby, a first space part 614a is formed between the base part end surface 615a and the first connecting band 613a. By providing the first space part 614a, the outer peripheral surface of the rod-shaped cosmetic material C inserted into the cosmetic material holding part 811 bites into the first space part 614a, so that the engagement of the rod-shaped cosmetic material C with the cosmetic material holding part 811 can be strengthened.

[0194] The second connecting band 813b is provided at a position axially spaced apart from the base part end surface 615a more than the first connecting band 613a. That is, the second connecting band 813b connects the long claw pieces 612b to each other in the circumferential direction at a position axially away from the base part end surface 615a more than the tip ends of the short claw pieces 612a. Thereby, a second space part 814b larger than the first space part 614a is formed between the base part end surface 615a and the second connecting band 813b. By providing the second space part 814b, the outer peripheral surface of the rod-shaped cosmetic material C inserted into the inner circumference of the cosmetic material holding part 811 bites into the second space part 814b, so that the engagement of the rod-shaped cosmetic material C with the cosmetic material holding part 811 can be strengthened. Therefore, even if the rod-shaped cosmetic material C is likely to move axially forward due to an impact or the like, the outer circumference of the rod-shaped cosmetic material C is caught by the rear end surfaces of the first connecting band 613a and the second connecting band 813b, so that the rod-shaped cosmetic material C can be prevented from coming off.

[0195] According to the above-described third embodiment, the same effects as those of the first and second embodiments are achieved.

[0196] As described above, the embodiments of the present invention have been explained. However, the above embodiments merely show a part of the application examples of the present invention, and are not intended to limit the technical scope of the present invention to the specific configurations of the above embodiments.
